Wash in Rate
are the change rates of apparent diffusion coefficient (ADC), pure diffusion coefficient (D), pseudo-diffusion coefficient (D*), perfusion fraction (f), maximum relative enhancement (MRE), time to peak (TTP) and Wash in Rate from pre-RT (2 weeks before radiotherapy) to post-RT (4 weeks after RT), respectively
- adenotes a significant correlation between the change rates of IVIM and DCE MR parameters
